I have this from amazon and use it every day have absolutely noticed a difference in my skin. It brought back that youthful glow that I missed (I swear to god this is not an ad). I also use it to calm my skin down when it gets irritated or when I need to speed up the healing after an infected pimple or something. The last time I got a facial my skin started to turn red and get itchy and irritated like it does sometimes, but I started using the red light and it calmed and never got bad.

I can't speak to the quality of that product, but I have this one and it's amazing. I have seen huge improvements in my skin and it's great for minor acute pain and inflammation. There's a clear price difference, but I have been using it daily since I bought it in February and believe it's worth the cost. I also question a product that's only $40.
